Pythagorean Espresso Cup / Mug

Sharing from Thingiverse, original design by Printrind.

This cup uses Pythagoras' original concept to punish greedy drinkers by using a syphon. If you fill the cup up to a certain level (around the height of the top of the handle), it will hold liquid with no issues, but as soon as you fill it past a certain point, the cup will "magically" drain itself until empty.

Recommended to be printed in PETG, not recommend for food use. Please be careful with hot liquids in the cup, it could drain and burn you.

Summary

This is a funny Pythagorean Espresso-Cup with the drainpipe hidden in the handle. The right thing for your guests at a dinner-party!

Instructions

Print with a bit more plastic to make the handle air-tight. This is important to ensure that the cup is fully emptied through the pipe.

It might also help to "bake" the cup for some time in the oven at about 50°C after it's printed.

I printed with PLA using a 0,35mm nozzle and without support structure. This should just about work for the overhang in the handle.
